Nitrate transporters and peptide transporters
In higher plants, two types of nitrate transporters, NRT1 and NRT2, have been identified. In Arabidopsis, there are 53 NRT1 genes and 7 NRT2 genes. NRT2 are high‐affinity nitrate transporters, while most members of the NRT1 family are low‐affinity nitrate transporters.

Controlled functional expression of the bacteriocins pediocin PA-1 and bactofencin A in Escherichia coli [PDF]
peer-reviewedThe bacteriocins bactofencin A (class IId) and pediocin PA-1 (class IIa) are encoded by operons with a similarly clustered gene organization including a structural peptide, an immunity protein, an ABC transporter and accessory bacteriocin ...

Glucose-induced down regulation of thiamine transporters in the kidney proximal tubular epithelium produces thiamine insufficiency in diabetes [PDF]
Increased renal clearance of thiamine (vitamin B1) occurs in experimental and clinical diabetes producing thiamine insufficiency mediated by impaired tubular re-uptake and linked to the development of diabetic nephropathy.

Effect of energy sources and levels on caecal microbial population, jejunal morphology, gene expression of jejunal transporters (sglt1, fabp) and performance of broilers under heat stress [PDF]
The present study was conducted to evaluate the effects of energy sources and levels on microbial population, jejunal morphology, gene expression of glucose transporter (SGLT1), fatty acid binding protein (FABP) and performance in broilers under heat ...

Transport Dynamics in a Glutamate Transporter Homologue [PDF]
Glutamate transporters are integral membrane proteins that catalyse neurotransmitter uptake from the synaptic cleft into the cytoplasm of glial cells and neurons. Their mechanism of action involves transitions between extracellular (outward)-facing and intracellular (inward)-facing conformations, whereby substrate binding sites become accessible to ...

Patched 1 reduces the accessibility of cholesterol in the outer leaflet of membranes
A long-standing mystery in vertebrate Hedgehog signaling is how Patched 1 (PTCH1), the receptor for Hedgehog ligands, inhibits the activity of Smoothened, the protein that transmits the signal across the membrane. We previously proposed (Kinnebrew et al.,

Uptake of purines in Plasmodium falciparum-infected human erythrocytes is mostly mediated by the human Equilibrative Nucleoside Transporter and the human Facilitative Nucleobase Transporter [PDF]
<b>Background</b>: Plasmodium parasites are unable to synthesize purines de novo and have to salvage them from the host. Due to this limitation in the parasite, purine transporters have been an area of focus in the search for anti-malarial ...

The transport fo self-propelled particles confined in 2D smooth corrugated channel [PDF]
Directed transport of self-propelled ellipsoidal particles confined in a smooth corrugated channel with asymmetric potential and Gaussian colored noise is investigated. Effects of the channel, potential and colored noise on the system are discussed. Large x axis noise intensity inhibits the transport.

Phosphorylation is required for the pathogen defense function of the Arabidopsis PEN3 ABC transporter. [PDF]
The Arabidopsis PEN3 ABC transporter accumulates at sites of pathogen detection, where it is involved in defense against a number of pathogens. Perception of PAMPs by pattern recognition receptors initiates recruitment of PEN3 and also leads to PEN3 ...
